Is there any other graphic library besides emWIN and Swim for the LPC1788?

Hi,

Development work is on going, but feel free to use emWIN in your projects.

What are you looking for?

EmWin is huge and doing a lot of amazing things, SWIM is small and just doing the basics :)

EmbeddedArtists has some kind of graphical library, coming with the code example for their LCD displays, and dev boards with LCD display.
It also implements just the basics (graphics primitives and text).
And I'm not sure about the licencing...

The main problem I have is that I need a bigger font type that SWIM supports. As I understand the biggest font type I can use with the SWIM library is winfreesystem14x16. Is it possible to use font types which size is bigger than that, at least 130x80 pixels with this library? If this is not the case what do you suggest to do?

Of course you can use your own fonts. And you could use a smaller font (like 65*40) and size it via software :)

Thank you very much for your answer:) but I still have a doubt. I think the biggest width value of a font using SWIM is 16pixels. I arrived to this conclusion after reading the implementation of [SIZE=2][B][U]swim_put_char [/U][/B][SIZE=3]Maybe I'm wrong but I'm not sure. :confused: Has anybody tried using bigger fonts before with SWIM and not using emWIN?[/SIZE]

Yup! You can!

This is 4.3" LCD 480x272
I am using swim_put_text_xy();
The font I am using here is free droidsans76.

My source code:
    swim_set_font(&G_win, &font_lpc_droidsansr76);
    swim_put_text_xy(&G_win, "76 PIXEL", 80, 50);
    swim_put_text_xy(&G_win, "YOU CAN!", 50, 150);

Google for fonts and play with them, you can even create a font set yourself and make them 300x300.

Hope this helps :)

Oh that cover is just a cut out plastic secured with black tapes so i can draw on it. Its really hard to program GUI using swim without some visual clue, at least for me

edited: Anyone got a cool idea how to simplify this process do give me a hint. emWin is too complex for me

Thank you for your help but I still believe YOU Can't (like [COLOR=#5174a3]vasanth[/COLOR] said), I'll be absolutely convinced only when you show me your code of the routine [COLOR=black][FONT=Courier New][COLOR=darkorange]swim_put_char()[/COLOR][/FONT][/COLOR][FONT=Helvetica-Bold][B] [/B][/FONT]that can be found in [COLOR=#2A00FF][FONT=Courier New][COLOR=darkorange]lpc_swim_font.c

[FONT=Times New Roman][SIZE=3][COLOR=#000000](If you dare)

Goodbye ! :p[/COLOR][/SIZE][/FONT]
